How to use optical power meter.
Optical power meter block diagram.
Average optical power can be measured easily and reliably with a relatively inexpensive optical power meter.
The output power meters is designed to directly measure the output power in an arbitrary load.
But a light source and power meter measurement does not indicate if.
The dominant noise sources in this section are the linear components that provide the optical to electrical conversion namely.
Otdr block diagram the otdr consists of a laser light source an optical sensor a coupler splitter a display section and a controller section.
A simple circuit is illustrated in fig.
Optical to arduino direct interfacing is possible via optical sfp modules.

The reason for this is contents 1.
With the exception of power meter calibration thermal power meters are rarely used in fiber optics.

The ability of simple arduino to optical interfacing will be advantages in some cable network and noisy environment like factory automation.
A modular optical power meter is provided which comprises a plurality of modules each of which contains a matched compatible set of elements consisting of a terminal connector a source of optical power and a sensor for sensing optical power.
In addition to power the output meter can be used to measure impedance and frequency response characteristics.
The instrument provides a set of resistive loads to be selected for power measurements.
Figure 1 shows a simple block diagram of the front end of an optical receiver.
